Valgrind errors

[sseraj]

Description

Running Valgrind on MACH-Aero optimization scripts results in numerous errors from ADflow and IDWarp, such as:
Conditional jump or move depends on uninitialised value(s) and
Use of uninitialised value of size 8

This issue is to discuss:

• What Valgrind options to use with MACH-Aero
• Which errors can be ignored
• Which errors should be fixed

Steps to reproduce issue

Run the MACH-Aero tutorial single point airfoil optimization with:
PYTHONMALLOC=malloc valgrind python airfoil_opt.py

Alternatively, run the ADflow adjoint test with:
PYTHONMALLOC=malloc valgrind python test_adjoint.py

The --error-limit=no option may also be helpful.
